Celestial Reasoning

This is a planetary gear based transmission for a Blue Point 3/8 inch drive air ratchet. The center gear is the sun gear. It is machined onto the end of the shaft coming from the pneumatic motor. The three gears around it are the planetary gears and they are meshing into the ring gear.

 

The unit’s purpose is that of gear reduction. It transforms the high speed of the motor to low speed high torque to the output shaft.

 

This air tool is used to quickly drive and remove nuts and bolts in a mechanical repair setting. The same sort of gearbox is used in hand held electric drill motors.

 

This frame is one inch wide.
